Hi I sent this message already some month before. I made some corrections to the boost random library because some generators don't fulfil the wg-21 specifications about the seed() method. I add the missing seed() methods to the following generators * linear_congruential * linear_feedback_shift * additive_combine * inversive_congruential * discard_block * shuffle_output Greetings Mario Index: linear_congruential.hpp =================================================================== RCS file: /cvsroot/boost/boost/boost/random/linear_congruential.hpp,v retrieving revision 1.15 diff -r1.15 linear_congruential.hpp 219c219 < void seed(int32_t x0) { lcf.seed(cnv(x0)); } ---
